From December 1, 2017, Aadhaar card holders can link their UID or Unique Identity Number with mobile number or SIM from the comfort of their home through an OTP (One-Time Pin) received on the mobile number registered with Aadhaar, according to the UIDAI. "No need to give finger prints to local SIM card retailer for your mobile phone verification," the UIDAI noted.

OTP or One-Time Pin is a mode of authentication offered by the UIDAI. Under one-time PIN-based authentication, an OTP with a limited period validity is sent to the mobile number and/or e-mail address of the Aadhaar number holder registered with Aadhaar. "The Aadhaar number holder shall provide this OTP along with his Aadhaar number during authentication and the same shall be matched with the OTP generated by the Authority," according to the UIDAI website.

What mobile users need to do

You can link your Aadhaar - the identification authenticated by your biometric details (fingerprint and iris scan) - with the mobile connection you are using by walking into a customer service centre operated by your telecom service provider. Telecom companies have urged their customers promptly in the recent past to complete the Aadhaar e-KYC process. (Read more)

Subscribers can verify or re-verify their mobile numbers from anywhere in the country irrespective of which service area their mobile connection belongs to, the telecom department added.
